If there were, I would expect it to work like this:

>> class Array
>> include Comparable
>> end
>> [1] < [2]
=> true
>> [1] < [1]
=> false
>> [1] < [1,0]
=> true

Array#replace already does that, except you have to give it the element 
also wrapped in an Array.

>> a = [1,2,3]
=> [1, 2, 3]
>> a.object_id
=> 69928599426960
>> a.replace [4]
=> [4]
>> a
=> [4]
>> a.object_id
=> 69928599426960
